Add Blink feature flag for decoding of lossy WebP to YUV

We can significantly speed up WebP rendering and reduce memory footprint
per image by decoding and storing lossy WebP images into their native
YUV format instead of unnecessarily converting to RGB.

This flag will be used to safely hide changes to the image decoding
paths until the feature is completely landed.

See bit.ly/webp-decoding-into-yuv for the design document and
crrev.com/c/1338461 for a working prototype CL in the GPU rasterization case.
